A good chat room for a 17 year old boy?

Can you suggest a nice British chat room for a 17 year old boy?

Hi!
One of my pupils is 17. He is learning English and would like to make friends. Do you know a nice chat room where he could meet boys his age and practise writing in English? Thanks
Update: He is from Pakistan so it is not easy for him to meet 'real' British people...
